加性个体噪声序列信道下的功率自适应反馈通信

Power Adaptive Feedback Communication over an Additive Individual Noise Sequence Channel

Yuval Lomnitz, Meir Feder

摘要:

我们考虑一个实值加性信道与一个单独的未知噪声序列。我们提出了一个简单的顺序通信方案的基础上著名的Schalkwijk-Kailath计划,它改变发送功率根据序列的功率,使渐近的SNR和速率之间的关系匹配高斯信道容量1/2 log(1+SNR)的几乎每个噪声序列。

英文摘要:

We consider a real-valued additive channel with an individual unknown noise sequence. We present a simple sequential communication scheme based on the celebrated Schalkwijk-Kailath scheme, which varies the transmit power according to the power of the sequence, so that asymptotically the relation between the SNR and the rate matches the Gaussian channel capacity 1/2 log(1+SNR)for almost every noise sequence.
